i know many of you guys know about this that frequent the h-t FI board but it is basically a standalone type fuel management system that is FREE and if you know how to write scripts you can add features to it. It seems on h-t nobody has been making h22 maps so maybe someone with some knowhow and desire that is on a low budget will try this, im just trying to spread the wealth, if you have an OBD2 h22 you need a chipped p72, batronix chip burner, obd2-obd1 harness and some tuning know how and you basically got similar standalone features in a free form

look here for the download

I've been trying to get a h22 basemap (out of a p72 map) for uberdata for months. Everyone who claims to have one is a complete asshole about giving it out or sharing any details, all they can say is SEARCH, so I suspect that means they don't really have one. I search my ass off and come up empty handed. My plan thus far is, buy a usdm obd1 p72, use the p72 basemap, change the fuel maps accordingly for the ludes 345cc injectors (4th gen vtec) then when i add dsm 450's mod them again. My only concern as of now is the timing maps, i have not a clue what to do since the p72 timing is already so retarded when running an h22, anyone have anything yet?

There are h22 basemaps on the pgmfi.org board for p28, p30 and p72. There might even be some for boost. The only possible issue is I don't remember if uberdata can open stock roms properly.

Shark- I think it might be worth trying to find an auto P13 ecu and seeing if it can communicate with the SS tranny computer, as the 4th gen autos had seperate boxes to control the transmission, too.
If so, there's been some good progress lateley on pgmfi on the p13, so you'd have control of rev and speed limits, as well as vtec engagement. Do some more footwork, and you can probably figure out to edit the fuel/ignition tables manually.
I'd there is a pretty good chance that the OBDI p13 uses a very similar protocol to communicate with the transmission box that the 5th gen ecu does. An easier way to test this would be try an auto P14 out of an accord or prelude S as the auto p13 is pretty rare (JDM only?)

Does anyone know if these will work w/ Uberdata?

Hrmmm, this might be worth checking out if I can source the equipment for cheap. Thanks for the tip, Jesse.

Nope, I have not found any, however I do have a spreadsheet of p13 values now for hi/lo ign/fuel tables. I got them from j davis on honda-tech and he got them somewhere off pgmfi.org that I could not find after 2 hours of searching. I don't have excel though so i can't open it:(

Yeah, I was reading/feeling your frustration on that uberlong uberdata thread over on honda-tech. Someone really needs to go in and prune that thing down.

So you'd take the values for the p13 map from the spreadsheet & enter them manually onto a b series chip?

This is pretty cool stuff . . . . one could theoretically be looking at stand-alone tuneability for the price of a P28, cheap laptop, $100 chip burner, and a wideband O2 sensor. Although you'd still need an OBDI conversion, plus tuning without the ability to datalog would be tedious - I guess the best move there would be to get that feature with your wideband.

And has anyone yet discovered what part of the code controls IAB's?

I will hopefully get all this stuff figured out by spring, my car's already obd 1, i'm just going to buy a p28, put the p72 code on a chip and enter the p13 values, and tune from there, and who says you need a cheap laptop? just lug along your desktop to the dyno :)

Yes- crome can change the IAB open/close on P72- p30 and p28 do not have the hardware to control IAB from the factory.

Would you mind emailing that to me? alphajesse@yahoo.com
Thanks.

Well, i finally did it, i have my car running in n/a mode off of a p06 converted to a p28 ecu, it pulls very nicely, i suspect if i tune it i can get low 14/high 13 1/4 mi timeslips with just tuning on the stock motor. I met a friend who already had everything to chip, I just bought a ecu off him and he made a map for me, works nicely, hoping to get it tuned here in a few weeks to see what the most power i can get out of a stock motor. My e-mail setup sucks, I have no problem sending you guys the spreadsheet if you can give me an alternative method of sending (IE: AIM). Let me know, my screen name is p3s7. After I learn a little more hopefully I can help you guys out some more :)

this sounds interesting. even though its too late for me, sounds like a pretty cool system. whats the cost of a p72? is it a chip that you install on the stock ECU or a piggyback or what?
 
#18 ·
I paid ~$300 for a p72 and obd2->obd1 harness from a po.com member.
You install the chip into the ecu. It is very similar to hondata, but without the "blue box" or the addon board they use. (That's so they can 'copy protect' roms made with their software.)
The main problem with uberdata and other DIY tuning solutions is that it is more difficult to find a shop that will work with this versus hondata. That means you have to do more work yourself.

since you're in a 5th gen you'd have to convert to obd1, buy a p72 or p28, $200 for p72 around $100 for a p28 (iab's is not that big a deal, i just run mine open all the time, thank you zip ties :)) It is no piggy back bull**** it's your actual map on your ecu that you edit, you have to socket your ecu yet (replace the stock chip with a socket you can insert chips on). There is a huge thread that has all this information on honda-tech, if you're really interested you should look there :)

im gonna take a look but i already have an AEM EMS, and i just cant see it lacking in features

its turbocharged with stock internals..
ah, shouldve known. i'd just figured he would have given some specs as to what turbo, at least. or what kit.

this looks like a great alternative, and im actually thinking about it for my bro with his type-r who wants to stay NA...
